1'0 LU iff/1 mit zit may concern:

Be it known that i, FnnDnRroKl/V. SCHARF- FER, a citizen of the United States, residing at Chicago, in the county of Cook and State oi Illinois, have invented a new and useful improvement in Fireproof l/Vindow Frames and Sash, of which the following is a specification.

This invention relates to a. window trame and sash; and the object oi the invention is a irame and sash which shall be iireproot, not only as to materials, but in construction, thereby preventing the entrance of tire into a building by way of the windows.

The invention consists of the novel features of construction and combination of parts hereinafter described, pointed out in the claims, and shown in the accompanying drawings, in which- Figure l is a perspective view of the window, Fig, 2 is a horizontal section taken through the 'frame and upper sash. Fig. 3 is a vertical section through the longitudinal center of the window.

channel-iron C, having an inwardly-extending iiange C, and upon the channel-iron or beam Cis bolted or riveted an angle-iron l), having one member-parallel with the flange C of that particular channel-beam, and a groove is thus formed between the ianges C and the angle-iron l) in each sash. A piece oi sheet-iron is secured to the under tace of the angle-bari) of each sash, as shown at E, and'is carried over the channel-beam and brought around to the liange C', and in the case of the lower sash a portion of the metal sheet E projects horizontally in the plane oi the upper edge of the beam C and 1s bent back upon itself, as at E', thus forming a weather-strip.

The lower horizontal rnernberof the upper sash is formed of a channel-beam Gr, having the upwardly-extending flange G and carrying an anglefiron H, arranged parallel to the 'flange G. A. piece of sheet metal E2 is secured to the inner tace of the angle-iron H sash is Jformed ot the channel-beam J and the arallel angled irons J, a metal sheeting E* A eing arranged between the angle-irons and the channel-beams. The glass K 'lits mtho grooves formed by means of the various channel-beam flanges C and G/ and the angle-irons D, H, and J and is packed with avsbestos, rubber, putty, or similar mater1al lx.

The Yfalse bottom A is supported or braced by al beam L, and in the space between the two bottoms A and A2 is arranged a trough L', communicating at its lower end with an outwardly and downwardly inclined chute L2, which discharges condensations of moisture. The frameAis bra-ced at the sides by the brackets or brace-rods A, and in the recesses of the trame A in which run the sashcs are arranged channehbeams M, in which the side channel-beams C slide. It willbe noticed that the various parts overlap and that a practically fireproof joint is formed when the sashes are in closed positions.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Fat-ent, is-

1. The combination with a sheet-metal frame recessed to hold the side members of a sash, el' channel-beams arranged in said recesses, and a sash having its sides formed oi channel-beams, the said beams being adapted to slide within the channel-beams et' the frame.

2. The combination with a sheetmetal window-frame, oi upper and lower sashes termed of channel-beams, said beams having an inwardly-extending flange, angle-irons carried by the beams parallel to the said Vflanges, glass panes held between the flanges and the angle-irons, and metal sheeting partially inclosing the channel-beams.

` 3 The combination with a sheet-metal window-frame, channel-beams carried by the frame, a sash comprising side members of channel-beams adapted to rest within and slide in theiirst-mentioned channel-beams, an upper sash member comprisin a channelbeam having an inwardly and c ownwardly extending flange, and angle-iron parallel to the iiange, metal sheeting mclosing the channel-beam and forming an air-space, a lower IOO IIO

side member comprising a channel-beam, at the bottom ofthe sash, as-and for the purparallel angle-irons earned thereby,1 metal pose set forth. V VVsheetin 'arran ed between the an e-irons and th said lwer Channel-beam agnd par- FREDERICK W SCHAEFFER 5 tally nclosing the same, and a pane held be- Witnesses:
